“…The ecological differences between the two Macroplea species are not yet fully understood. Macroplea mutica and M. appendiculata are regarded as sister species (Kölsch et al , 2006), for which a difference in habitat choice is usually assumed. The former species prefers brackish water, whereas the latter occurs in freshwater (Freude et al , 1966; Mohr, 1985).…”

Leaf beetles of the genus Macroplea live permanently under water. Species-specific preferences for either freshwater or brackish water are available in the literature. To detect potential physiological differences, the oxygen consumption of Macroplea mutica and Macroplea appendiculata from habitats with differing salinities is measured at two different salinities (0 and 10). The specific oxygen consumption does not depend on oxygen saturation of the water (values in the approximate range of 25-100% occur during the experiments). There is no difference between species or sampling locations. Similarly, the salinity during the measurements does not affect the oxygen consumption of the beetles, either when compared as salinity per se (0 versus 10), or when classified as home salinity or atypical salinity. Comparisons with other chrysomelid beetles and aquatic insects (using available published data) reveal that the two Macroplea species have relatively low metabolic rates. This finding is discussed in the light of activity patterns and morphology, especially the reduction of flight muscles, which comprise a highly metabolically active tissue.

“…They puncture the aerenchyme of the plant with two hollow abdominal hooks that are directly connected to their tracheal system. Macroplea occurs in Eurasia with some overlap in species distribution (Borowiec 1984;Ko¨lsch, Bistro¨m and Pedersen 2006;Ko¨lsch and Pedersen 2008). To the current knowledge, Macroplea mutica (Fabricius, 1792) is most widely distributed.…”

The aquatic leaf beetle species Macroplea mutica and M. appendiculata (Coleoptera, Chrysomelidae, Donaciinae) differ in their use of Myriophyllum spicatum as a host plant As a contribution to the continuing discussion of the ecological differentiation and stable coexistence of species, we investigated the extent to which the two sister species, Macroplea mutica and M. appendiculata, use the host plants Myriophyllum spicatum and Potamogeton sp. Specimens from four populations differing in host plant experience were used for behavioural observations. Both species did not feed on Myriophyllum but on Potamogeton. Beetles kept on Myriophyllum or without plant lost weight, while those on Potamogeton maintained or increased their weight. Only M. appendiculata laid eggs on this plant, as well as on Potamogeton, where M. mutica exclusively oviposited. In choice experiments, all larvae preferred the roots of Potamogeton over Myriophyllum for attachment (also the M. mutica larvae that had been collected from Myriophyllum). The data are discussed in the light of the unusual occasional occurrence of M. mutica on Myriophyllum and the speciation in the genus Macroplea.

“…Mann & Crowson (1983) classify the hindwing venation of Macroplea as "most reduced known in Donaciinae", which supports a reduced ability to fly. However, this striking immobility in and out of water did not prevent the genus from colonising Northern and Central Europe (as well as other parts of the Palearctic; Borowiec, 1984;Kölsch et al, 2006) after the last ice age, which must have been by passive dispersal (see Discussion).…”

Abstract. The pattern of postglacial re-colonization of Europe and the present population structure are known for various plant and animal species. The reed beetle Macroplea mutica (Fabricius, 1792) has characteristics that should influence both aspects in a peculiar way and therefore complement the currently known scenarios: It is fully aquatic but cannot swim or fly. Samples from 25 European populations of M. mutica and five specimens from China were investigated using amplified fragment length polymorphism (AFLP, 251 loci). Assessment of error rates associated with this method showed that the data set contains a strong population genetic signal. As hypothesized pronounced population differentiation and signs of inbreeding were found. Italian populations are clearly differentiated from northern populations (and from each other), which underlines the role of the Alps as a major barrier. Specimens from Lake Balaton (Hungary) show some affiliation with the populations in the Baltic Sea, which are all relatively similar. Populations from the eastern part of Northern Germany are similar to the Baltic populations, while those from the western part are allied to the British populations. The hypothesis is that the recolonization of Europe was from both the Southeast and a western refugium in the area of present-day southern England or Ireland, which resulted in a suture zone in Northern Germany. The effect of passive dispersal by drift attached to host plant material (especially in the Baltic Sea) and by zoochory (migrating waterfowl) is discussed.
